About this file

This document contains an amendment to a solicitation for replacing Chiller #2 at the Nashville Campus of the Tennessee Valley Healthcare System. The amendment provides answers to questions from potential offerors. It clarifies that four new 1600 amp feeders are required from the existing switchboard to the automatic transfer switch to support the new chiller. It also specifies that a 1600 amp feeder and disconnect are needed between the automatic transfer switch and the new chiller, rather than reduced 800 amp components as originally illustrated. Commissioning of the automatic transfer switch will be covered under a separate electrical project. The breaker size in the main switchboard is to be determined by the separate contractor performing that work. Coordination is still required for installation. The related federal contract opportunity specifies this is solicitation number 36C24923B0023 from the Department of Veterans Affairs for replacing Chiller #2 at the Nashville Campus of Veterans Integrated Service Network 9. The bid opening is scheduled for October 24, 2023 at 1:00 PM Central Time, which will occur via Microsoft Teams.

CONTINUATION PAGES

The SOW states to “furnish and install (4) new feeders from the existing switchboard MSBA for normal power to ATS -19 in room E-26. Provide and install 480 volt breaker and disconnects to support new chiller to switchboard MSBA”:

1. What size are these (4) feeders? On the one line that was provided the Normal side feeder from ATS 19 to panel MSBA has a note tag of 760. The feed from the new 1600 amp disconnect to the chiller also has a note tag of 760. I assume this is an 800 amp feeder since the disconnect is fused at 800 amps. Please advise size and quantities.

Answer: 760 indicates amperage to existing chiller that will be demo’d as a part of this project. Size all feeders for 1680A new Chiller #2.

2. Are we to provide the new 1600 amp feeder shown on the one line drawing between the ATS 19 and the new 1600 amp disconnect?

Answer: Yes.

3. Are we to provide the reduced 800 amp size feeder from the new 1600 amp disconnect to the new chiller #2 shown on the one line drawing?

Answer: No, provide 1600 amp feeder from disconnect to new Chiller #2.

4. Are we to provide the 1600 amp disconnect fused at 800 amps for the new chiller #2?

Answer: No, provide 1600 amp disconnects.

5. In the government provided SOW C.4, the last sentence states “Contractor to include VA required commissioning of ATS 19”. We cannot provide commissioning of another contractors provided ATS. The providing contractor should include this as a part of their scope for warranty purposes. Please advise.

Answer: Commissioning for ATS will be included in a separate Electrical Project.

Project: 626-24-201, Replace Chiller 2 at the Nashville Campus

Solicitation: 36C24923B0023

Amendment: 0003 - RFI Answers

6. What size frame and breaker are to be provided in MSBA since the feeder is a reduced size to 800 amps but has a 1600 amp ATS and disconnect?

Answer: Breaker provided by separate contractor, coordination for installation still required.
